I have a Toshiba Satellite L505-GS6000 and was looking to upgrade my ram so my computer would run faster. one reason I am doing this is an online game I used to play all the time wont play very well, the fps is good but after about 4 mins of playing the game starts freezing every 4-5 seconds. my question however is while looking for ram to put in my computer I found a Corsair 8GB PC8500 DDR3 1066Mhz SODIMM Memory - 2x4096MB or Patriot PSD316G1333SK Signature Laptop Memory Kit - 16GB (2 x 8GB), PC3-10600, DDR3-1333MHz, 1.5V, CL9, Non-ECC, Unbuffered. I wasnt sure which would be better for my laptop an give it the best speed. also what does the Unbuffered mean? I was also wanting to make sure the Ram memory kits would fit in my laptop. Thanks
